What temperature kills germs in the house? Hot temperatures can kill most germs — usually at least 140 degrees Fahrenheit. Most bacteria thrive at 40 to 140 degrees Fahrenheit, which is why it’s important to keep food refrigerated or cook it at high temperatures.
Do germs live better in hot or cold weather? Cold temps create ideal conditions
It’s a myth that cold temperatures themselves cause the cold or flu. But the viruses that cause these infections thrive in dry, cold conditions. What’s more, cold weather changes the way our bodies respond to disease and makes us behave in ways that can increase the risk of infection.
How cold does it have to be to kill bacteria? It is a myth that bacteria are killed at temperatures below 40 degrees. In fact, bacteria growth is slowed, but not stopped. The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees or more. Bacteria also die in highly acidic environments like pickle juice.
Why do hospitals keep it so cold? Hospitals combat bacteria growth with cold temperatures. Keeping cold temperatures help slow bacterial and viral growth because bacteria and viruses thrive in warm temperatures. Operating rooms are usually the coldest areas in a hospital to keep the risk of infection at a minimum.
